Robin Williams had so much joy in this, its so wonderful and heartwarming! Quite a few bleak characters and things that could have been avoided, otherwise I'd give it a 10. Excessive happiness should be fine, I don't understand why there's a boss that is a Debbie Downer, yeah ok he's serious about his job, but lacking sense of humor that is important for patients to enjoy. This is a powerful film and makes me bummed that Robin Williams is gone!
